Must have had several seeds stuck together. No way 1 seed will produce 4 plants. :)

I assume you know these were hybrids so likely won't breed true? Could still be very good anyway. You will want to transplant and separate them soon before the roots get too entangled. Good luck.

I actually didn't know they were hybrids. How much bigger should I let them get before I separate them? Thanks for the luck! :)

Most all the colored peppers are hybrids and any store-bought peppers with the exception of red chilis and jalapeno will be too.

You can separate and transplant them now. The sooner the better given how close they are growing together. Just handle them by the leaves not the stems.
